Hi Tristan
Just looking at the magfld routine your magnetic field intensity and direction cosines look strange:
Are you sure B is always larger than zero (e.g. at very negative Z) ? The returned direction cosines are not normalized either..
Can you please verify before I go further?
Cheers
Stefan
BTY = 0.D+00
* solenoid field is at 14 degrees to target
vcos14=0.970
vsin14=0.242
* find B as a function of x and z positions (x and z are perpendicular and aligned with the target respectively)
zcl=Z*vcos14-X*vsin14
if (zcl.lt.50) then
B=2.5+1*((zcl-50)/100+2.5)
endif
if (zcl.ge.50) then
B=5-2.5*(zcl/100)
endif
* define direction cosines
BTZ=vcos14
BTX=vsin14

Subject: [fluka-discuss]: FLUKA model with magnetic field - TIMED OUT error
Dear FLUKA experts,
I am running a FLUKA model with a user routine for the magnetic field. The user routine appears to be correctly compiled and I can view the magnetic field in FLAIR geometry plot and it looks as I expect. Half way through the simulation FLAIR reports that it has "timed out" and does not write a results file. I find it is filling up my available disc space with huge multi Giga Byte files. I think it is the huge files that may be causing the time out problem.
Can anyone explain why this is happening and what I could do to get my simulation to work normally?
I attach the input file and the magnetic field user routine.
Many Thanks
Tristan
